Specification of Letters Patent.

Application filed September'17, 1906. Serial NO- 334,839.

Batented Dec. 31,1907.

To all 'whom it may concern:

Be it known that L-JAMES W. WANDEILL, I

adelphia, in the county of. Philadelphia and State of Pennsylvania, haveinvented new and useful Improvements in Harrows, of

' necte ment may be drawn by animal-power, and' which the following is aspecification.

This invention relates to disk plows or har rows, the object oftheinvention being to provide a simple, strong and durable construction ofmachine provided with cutting wheels or disks arranged to both out andgive a lateral stirrin motionto the soil, so as to eflect'a thorougpulverization thereof.

Another object is to provide pulverizing devices of this characterdriven positively b motor mechanism on the frame, which pufverizingdevices are permitted to have vertical play or movement to adaptthem tofreely pass over obstructions without injury.

A still further object is to wheels or disks havin whereby those teeth w'ch are injured or broken or become dull may be conveniently detachedand others substituted therefor and the invention consists in theconstruction provide cutting and arrangement of parts, as will behereinafter described and particularly pointed out inthe claims.

In the accompanyin drawings Figure 1 is a side elevation of a dis plowor harrow embodying my invention; Fig. 2 is a top plan view of the same;Fig. 3 is a rear end elevation of the implement; Fig. 4 is a side viewof one of the cutting wheels or disks; and Fig. 5 is a transversesection-thereof.

Referring to the drawings, ldesignates the frame of the implement whichmay be of any preferred form and construction. The frame is mounted uponfront and rear sets of supporting wheels or rollers 2 and 3, mountedrespectively on front and rear axles 4 and. 5. A ton e or other draftdevice 6 ma E with the front axle so that tlie implethe front axle hasthe usual fifth-wheel connection with the frame to allow theimplementtobe conveniently steered.

The frame is provided with rearwardly extending bracket plates 7provided with arcuate bearing slots 8 in which are journaled the ends ofa transverse shaft 9, carryin at each;

end a sprocket wheel 10. The whee s 10 are connected by chains 11 withcorres cnding Wheels 12 on a transverse motor shaft 13 journaled inhearings on the front portion of UnitedStates, residing at Philremovableteeth,

the frame. Shaft 13 maybe driven by an 3'," preferred type of.hydrocarbon motor 12', mounted upon the frame and supplied withhydrocarbon from a tank or reservoir 15. The operation of the motordrives the shaft 13 which, through the gearlng just described,

transfers motion to the rear transverse shaft 9.

On the shaft 9 are cutting disks or wheels 15 provided with cuttin teeth16. These are arran ed at an o lique angle on the ve thereshaft, and areed thereto to revo with-so that as-the shaft turns the wheels will begiven a rotary motion in the direction of revolution as well as alateral or sidewise motion, thus causing them in effect to Wabble asthey rotate. in additionto cutting into the soil also serve to loosenand stir the same, the soil to a fine condition.

Each cutting wheel or disk comprises a hub formed of a pair of clampingplates 17 having coinciding sleeves 18 bored at an angle for the passageof theshaft 9 and rovided with clam ing screws 19 to fasten t 18 samethus pulverizing Bythis means the disks, I

-scription, and it will be apparent. that the invention provides a simpe and efficient type ofcuttin row the soil.

I wish it to be understood that the rear ends of the brackets arecut-awayin right angular shape to provide downwardly extensions 8, .mwhich and said brackets the arcuate slots are formed. Further, the cutaway portions also form portions 22, to which 1 is secured a transverseshield or hood 22,

g mechanism to plow or harsaid shield being arranged over the rearportions ofthe disks and serve to prevent the soil from fiyin upwardabove the same.

If desired, t e motor may be geared with either the frontorrearwheelsofthe vehicle,

so that it may be used to drive the vehicle as well. as the cuttingmechanism. Planting and fertilizing devices may be arranged upon thevehicle, so that the operation of fertiseed of any desired ind may besimultanewardly projecting portions, said extensions Q mama and platesbeing provided with arcnate slots; an axle mounted in said slots andhaving angular disks thereon, means for rotatin said shaft, and atransverse shield secure to said rearwardly. projecting portions,substantially as. described,

In testimony whereof I affix my signature presence of two witnesses. I r

Having thus described the inVentiomwhat I claim is:

A plow o1 barrow comprising a wheeled i supporting frame, platesprojecting rear-i wardiy and s'ecured'to' the opposite, sides of l inthe frame, said plates being cut-away at theirrear portions in rightangular form to I provide downward extensions and rear- Witnesses:
